}

RangeQueryInfo encapsulates the details of a range query performed by a transaction during simulation. This helps protect transactions from phantom reads by varifying during validation whether any new items got committed within the given range between transaction simuation and validation (in addition to regular checks for updates/deletes of the existing items). readInfo field contains either the KVReads (for the items read by the range query) or a merkle-tree hash if the KVReads exceeds a pre-configured numbers
